Audio transducers and buzzers are used in electronic equipment, toys and various warning devices as sounding components. They can be either electromagnetic or piezoelectric in operation. Electromagnetic transducers generate either a single continuous sound or intermittent tones and are available with either self-contained or external drive circuitry. Piezoelectric transducers include a metal plate that vibrates with the expansion or contraction of a piezoceramic element. Some audio transducers can transmit signals, some can receive signals, and some can both transmit and receive signals.

Audio transducers and buzzers vary according to tone, frequency, and sound pressure. Some devices have an alarm with a continuous tone, while others have an alarm with a pulsed or non-continuous tone. The frequency measures the number of events or cycles that occur in a time period, usually one second, in Hertz (Hz). The sound pressure level (SPL) measures the loudness or volume in decibels (Db). A 10 Db increase in SPL represents a doubling in volume. In terms of electrical specifications, audio transducers and buzzers also vary by operating voltage rating, maximum operating current, and operating temperature.
